The polynomial function p(x) = 5[tex]x^{3}[/tex] +8[tex]x^{2}[/tex] - 3x +1 value at x = -2 is -1
given that
polynomial function p(x) = 5[tex]x^{3}[/tex] +8[tex]x^{2}[/tex] - 3x +1 at x=-2
To find the value of a function at x = -2, put in all the places of in the function.
Polynomial is made up of two words, poly, and nomial. "Poly" means many, and "nomial" means the term, and hence when they are combined, we can say that polynomials are "algebraic expressions with many terms".
Polynomial functions are expressions that may contain variables of varying degrees, coefficients, positive exponents, and constants.
Here,
p(x) = 5[tex]x^{3}[/tex] +8[tex]x^{2}[/tex] - 3x +1 put x =-2
p(-2) = 5[tex](-2)^{3}[/tex]+8[tex](-2)^{2}[/tex] - 3(-2)+1
p(-2) = 5(-8) + 8(4) + 6+1
p(-2) = -40+32+6+1
p(-2) = -40+39
p(-2) =-1
At So, the value of the function at x= -2 is -1
